Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates mainly to dogs and cats bred at home, small animals such as rabbits, birds and hamsters, and various odors generated from their breeding environment. The present invention relates to a deodorant composition having an excellent deodorizing effect without having a strong fragrance and having high safety for a human body and a pet.

[0002]

BACKGROUND OF THE INVENTION Generally, malodors generated from animals include organic compounds containing nitrogen and sulfur such as ammonia, hydrogen sulfide, mercaptan, and methyl sulfide generated from manure, or decomposition of proteins. There are lower fatty acids such as butyric acid and valeric acid generated from products and body odor. Most of the malodors generated from and around pets kept at home are mixed odors. Heretofore, as a method of eliminating these bad smells, a method of using a substance having a very strong aroma as a deodorant and masking the bad smell by the aroma has been mainly employed. However, since such a deodorant uses a fragrance that is stronger than the odor intensity, the intensity of the odor after mixing with the odor becomes significantly stronger than the original intensity, resulting in unpleasant sensation. May be used. In addition, pets with a more sensitive odor than humans often dislike the odor of the deodorant. As a method for eliminating other offensive odors, there is a method using a chemical reaction caused by ozone, glyoxal, hypochlorite, etc. However, there is a great limitation in terms of safety for pets and human bodies. Accordingly, the present invention has an excellent deodorant effect on dogs and cats mainly bred at home, rabbits, small birds, small animals such as hamsters, and any odor generated from the breeding environment,
Moreover, it is an object of the present invention to provide a highly safe deodorant composition which does not have a strong fragrance itself.

[0003]

Means for Solving the Problems The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have found the following, and have completed the present invention. First, a plant extract was selected for a deodorant base material that meets this purpose, in consideration of the deodorant effect and safety of a malodor generated mainly from a pet and its surroundings. Next, when the deodorant composition capable of effectively exhibiting the deodorizing function of the plant extract was examined, the following problems occurred. The malodor reacts with the deodorant base material by dissolving in the deodorant solution. However, the main foul odor generated from pets and their surroundings is acidic odor or alkaline odor,
When these dissolve, the pH of the solution tends to be acidic or alkaline, so that the solubility of the offensive odor in the deodorant solution is reduced, and as a result, the deodorizing effect is reduced.

[0004] Therefore, the deodorant composition containing a plant extract is adjusted to a weakly acidic region with a specific acid or alkali and has a specific buffering action, so that the pH at the time when the malodor is dissolved is adjusted. By suppressing the change and alleviating the decrease in the solubility of the malodor, the effect of the plant extract serving as the deodorant base was significantly enhanced. That is,
According to the present invention, (a) a plant extract as a deodorant substrate,
(B) a weakly acidic deodorant composition containing an organic acid and / or a salt thereof, and (c) a weakly alkaline agent, wherein the composition is
The deodorant composition is characterized in that the buffer capacity is adjusted so that the addition amount becomes 8.0 g or more when a 1 mol / L aqueous ammonia solution is added to 0 g until the pH becomes 7.0. Provided.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The plant extract of the component (a) used in the present invention is not particularly limited as long as it has a deodorizing function. For example, oxalis, prickles, hemlock, ginkgo, black pine, larch , Japanese red pine, holly, holly mokusei, lilac, golden finch, butterflies, camellia, forsythia, chestnut, alder, oak, pomegranate, fig, spring, spring cypress, oyster, psyllium,
Examples include extracts extracted from mugwort, bay maple, cabbage squirrel, white-bellied hagfish, lobster, fern, porcupine, coba ash and sugar cane. These plant extracts can be used alone or in an appropriate combination of two or more.
Among the plant extracts, the sugar cane extract is preferably contained in the component (a) because of its high deodorizing effect and excellent safety. As sugar cane extract, for example,
MSX-245 manufactured by Mitsui Sugar Co., Ltd. can be used. Examples of products containing a plurality of plant extracts include “Super Puriere A-10” (manufactured by Matsushita Electric Works, Ltd.), “Smeral” (manufactured by Environmental Science Development Co., Ltd.),
“Pancil” (manufactured by Release Kagaku Kogyo Co., Ltd.) and the like can also be suitably used. The amount of the plant extract is preferably 0.1% by mass or more.
Particularly preferred is 3% by mass or more. When the amount is less than 0.1% by mass, the deodorizing effect is not sufficiently exhibited, which is not preferable.

The organic acid and / or salt thereof of the component (b) used in the present invention is not particularly limited, but citric acid, malic acid, and food additives are considered in consideration of safety for pets and the like. Adipic acid, fumaric acid, lactic acid, gluconic acid, maleic acid, succinic acid and their sodium salts,
Potassium salts, magnesium salts, calcium salts and the like are preferred. The amount of the organic acid and / or salt thereof is preferably from 1.0 to 5.0% by mass, particularly preferably from 2.0 to 5.0% by mass in order to sufficiently exert the deodorizing power. If the amount is less than 1.0% by mass, a sufficient deodorizing effect may not be expected. If the amount exceeds 5.0% by mass, stability at low temperatures may be deteriorated.

The weak alkaline agent of component (c) used in the present invention is not particularly limited, but amine compounds such as monoethanolamine, diethanolamine and triethanolamine are preferred, and triethanolamine is particularly preferred. . The weak alkaline agent has a stronger pH buffering action in a weakly acidic region than a case where a strong alkaline agent such as sodium hydroxide or potassium hydroxide is blended, and realizes a high deodorizing performance especially for alkaline odor. The compounding amount of the weak alkaline agent is appropriately compounded in a range that satisfies the target pH and buffer capacity.

[0008] The deodorant composition of the present invention is (b) an organic acid and / or a salt thereof, and (c) weakly acidic with a weak alkaline agent, specifically, a pH range of 4.0 to 5.5. The buffer capacity is adjusted so that the addition amount when adding 1 mol / L aqueous ammonia solution to 100 mL of the deodorant composition until the pH becomes 7.0 becomes 8.0 g or more. When the pH is less than 4.0, a problem is likely to occur in the stability of the solution, and further, skin irritation may occur when the pet is accidentally sprayed. If the pH exceeds 5.5, sufficient deodorizing performance cannot be exhibited. In addition, by adjusting the buffer capacity as described above, the pH when various malodors generated from pet manure and the like are dissolved in the deodorant solution.
The effect of the plant extract, which is the deodorant base material, can be enhanced by suppressing the change in the odor and reducing the decrease in the solubility of the offensive odor. In general, malodors are divided into acidic odors and alkaline odors, and these malodors react with the deodorant base material by dissolving in the deodorant solution and are deodorized. At this time, the higher the buffer capacity of the solution, the greater the amount of the malodor dissolved, and the higher the deodorizing effect.

Further, the deodorant composition of the present invention may contain optional components as needed, as long as the effects of the present invention are not impaired. Optional components include water, surfactants, hydrotropes, bactericides, preservatives, fungicides,
Dyes, antioxidants, thickeners, gelling agents, ultraviolet absorbers and the like can be mentioned. Further, a fragrance and an essential oil can be blended as optional components, such as 1-menthol, menthol, cinamic aldehyde, 1,8-cineole, α-pinene, citronellol, geraniol, linalool, limonene, camphor, lavandulol and the like. Aroma components, citronella oil, cedarwood oil, sweet orange oil, bergamot oil, lavender oil, rose oil, cinnamon oil, peppermint oil, lemon oil, lime oil, hinoki oil, or a mixture thereof, It is not limited to these. Note that these optional components are not particularly limited as long as they are used in a general deodorant.

[0010] The form of use of the deodorant composition is not particularly limited. For example, sprays, liquids, impregnation into a carrier, powders, tablets, granules, etc., and various dosage forms can be used in a wide variety according to the application. It can be selected and the production method can also be produced using commonly used components according to each use and dosage form. Among them, the spray type is preferable in that it can easily and uniformly act on places or objects where odor is generated, pets, and the like.

The deodorant composition of the present invention is suitably used mainly in pets and their breeding environment, but is not necessarily limited thereto, and may be used in toilets, living rooms, bedrooms, kitchens, entrances, and sanitary articles. , Excrement, cigarettes, pets, diapers, clothing, air conditioners, garbage, refrigerators, shoes,
